An official of the European Central Bank (ECB) recently said that all cryptocurrencies are not created equally, Bloomberg reported.

Speaking in Paris this week, Francois Villeroy de Galhau said that he sees a role for stablecoins – digital tokens pegged to fiat currencies – in the financial system.

The Bank of France is “observing with great interest initiatives in the private sector which aim at developing networks within which ‘stable coins’ would be used in transactions involving ‘tokenized’ securities or goods and services,” he said. “These are quite different from speculative assets like bitcoins, and more promising.”

Earlier this month, ECB President Mario Draghi called cryptocurrencies as “highly risky” assets, CCN reported. Responding to a question asked by student on cryptocurrencies, he said:

“Bitcoins or anything like that are not really currencies, they are assets. A euro is a euro – today, tomorrow, in a month, it’s always a euro. And the ECB is behind the euro. Who’s behind the cryptocurrencies? So they are very, very risky assets, the value of which oscillates – as you’ve seen – wildly.”
